hey guys first post here. just got the SR for my gf for christmas. awsome phone but her battery life just sucks. she can't even get through her day without it going dead. i looked at the usage and display always takes about 50% of the battery even with brightness turned all the way down.

this are screen shots from today. her battery is at 19% after 11 hours but screen was on for only 2 hours so it means that she used it for that long plus about 20 mins of phone calls. Should we take it back?? is this normal?? thanks

Android phones tend to have short battery life. There are some things to do to extend the battery. But, first you need to teach Android about your battery. Otherwise, your phone's battery meter is likely to be very inaccurate.

You only need to do this one time. After fully charging the battery, use the phone, but leave it on until it finally shuts down because of low/dead battery. The Android system will then have a good representation of your battery life, making its battery meter more accurate. Because there are only so many cycles for the li-on battery, you should avoid fully discharging the battery after the one full discharge.

Try to keep the battery charged up as much as possible. I have a desktop charger, car charger, and put my phone on a charger when I go to bed at night. I also have a couple of spare batteries that I keep charged up in an AC charger to swap in and out of my phone. I've probably gone a little bit overboard, but you get the point.

There are some general things you can do to preserve battery life.

Keep the wi-fi turned off unless you are using it.

Set up your phone to sync calendars, e-mails, and contact only at specific periods (once an hour, once every 3 hours, etc.) rather than constantly sync, or setup to allow only manual syncs. The phone can also be set up to use a dimmer screen setting and shut off the screen (screen timeout) after a short period of inactivity. Some phones have an auto-screen setting that automatically adjusts the screen brightness to the light conditions which uses only as much battery power as needed.

Just doing the above should improve the battery life. Let me also note that when first getting a phone, it tends to have a short battery life because you are playing with it all the time "new toy syndrome."

Some people suggest turning off the GPS, but it does not use any power unless an app needs it. I keep my GPS setting turned on.

If new to Android, after using an app (checking e-mail, playing game, etc.), use the back key, (U shaped arrow on my phone) to turn off the app, rather than clicking on the Home key. Used up batteries quickly with one particular game app that stays active until I started using the back key.
